Introduction
Hi! I’m Shreyas 👋, a developer on a 90-day mission to master DevOps. I’ll be learning and sharing my progress daily with bite-sized insights. If you're curious about DevOps or just starting your journey, let’s explore it together! 💡
So this is the Day 1 of my journey. Lets gets started:
What is DevOps?
DevOps is a culture, methodology, and set of practices that unify software development (Dev) and IT operations (Ops). It emphasizes:
- Collaboration: Developers and operations teams work together.
- Automation: Replacing manual tasks with tools and scripts.
- Continuous Integration/Continuous Deployment (CI/CD): Ensuring rapid, reliable software delivery.
Key Benefits of DevOps
- Speed: Faster release cycles and quicker feedback.
- Quality: Automated testing reduces bugs.
- Scalability: Efficient processes make scaling applications seamless.
The DevOps Lifecycle

- Plan: Define the project goals, requirements, and workflows.
- Develop: Write and collaborate on code using tools like Git.
- Build: Package the code into deployable artifacts.
- Test: Validate functionality to catch bugs early.
- Release: Manage versions and prepare for deployment.
- Deploy: Push code to production or staging environments.
- Operate: Maintain infrastructure and application stability.
- Monitor: Observe performance and gather feedback for improvements.
What is CI/CD?
Continuous Integration (CI)
A devOps software development practice where the developer regularly merge their code changes into a central repository, after which automated builds and tests are run.
How it works:
- Developers push code changes to a version control system (like Git).
- A CI server (e.g., Jenkins, GitHub Actions) automatically builds and tests the code.
- If the build or tests fail, the developer is notified.
Benefits of CI:
- Prevents integration issues (the "it works on my machine" problem).
- Ensures a stable codebase.
- Saves time by identifying bugs early.
Continuous Deployment/Delivery (CD)
- Continuous Delivery: Ensures code changes are always in a deployable state. Deployment is manual but can be triggered with a single click.
- Continuous Deployment: Takes Continuous Delivery one step further by automating the deployment process. Code changes that pass tests are automatically deployed to production.
How CD works:
- After successful CI, the application is built and packaged. Automated tools deploy the application to staging and production environments.
- Monitoring tools ensure the new version works as expected.
Benefits of CD:
- Reduces manual effort and risk of human error.
- Speeds up the feedback loop between users and developers.
- Allows teams to focus on building features rather than deployment.
Key Takeaway
Day 1 was all about setting the foundation for my DevOps journey. Understanding the principles of DevOps, the lifecycle, and the concepts of CI/CD has been an exciting start! 🚀
I’m thrilled to continue this learning adventure, diving deeper into tools, technologies, and best practices in the coming days. Stay tuned, and let’s master DevOps together one step at a time! 💡
